Abstract :
This paper describes a new class of electric motor, with a field winding and an armature winding, both of which are on the stator. The motor has no brushes or permanent magnets. Its motor characteristics are shown to be similar to those of a DC machine. Control of the armature windings can be achieved with very simple electronic circuits resulting in a very low cost and reliable variable speed drive. An experimental flux switching motor has been constructed and tested in conjunction with two new power converter circuits
